Hi everybody,
I'm from Viet Nam, now i'm a developer. In my project, I use DIB to store my bitmap. This Bitmap is 24 bit CMYK. But I want to Dithering this Bitmap to 4bit CMYK. I don't know any dithering algorithm for this task.
Any body can help me?
Thanks much!

Hello Minhcom,
Are you sure you are working with CMYK bitmaps? CMYK has 4 color channels, so it usually occupies 32 bits. Anyway, GDI does not support any CMYK pixel formats (at least officially).
If you mean RGB, you can do it with Graphics Mill.
P.S. Note, Graphics Processor is discontinued product. You should use Graphics Mill instead (unless you have a lot of legacy code with Graphics Processor).
P.P.S. If you have any questions regarding Graphics Mill, please post a message to Graphics Mill forum.
